ES58x devices report below product information through a custom usb
string:
* the firmware version
* the bootloader version
* the hardware revision
Parse this string, store the results in struct es58x_dev, export:
* the firmware version through devlink's "fw" name
* the bootloader version through devlink's "fw.bootloader" name
* the hardware revisionthrough devlink's "board.rev" name
Those devlink entries are not critical to use the device, if parsing
fails, print an informative log message and continue to probe the
device.
In addition to that, use usb_device::serial to report the device
serial number.

IMX93 do not contain a GPR to config the stop mode, it will set
the flexcan into stop mode automatically once the ARM core go
into low power mode (WFI instruct) and gate off the flexcan
related clock automatically. But to let these logic work as
expect, before ARM core go into low power mode, need to make
sure the flexcan related clock keep on.
To support stop mode and wakeup feature on imx93, this patch
add a new fsl_imx93_devtype_data to separate from imx8mp.

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.
It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

There are cables that exist that can support speeds in excess of 10GbE.
The driver, however, restricts the EEPROM advertised nominal bitrate to
a specific range, which can prevent usage of cables that can support,
for example, up to 25GbE.
Rather than checking that an active or passive cable supports a specific
range, only check for a minimum supported speed.

SFP+ active and passive cables are copper cables with fixed SFP+ end
connectors. Due to a misinterpretation of this, SFP+ active cables could
end up not being recognized, causing the driver to fail to establish a
connection.
Introduce a new enum in SFP+ cable types, XGBE_SFP_CABLE_FIBER, that is
the default cable type, and handle active and passive cables when they are
specifically detected.

It should use dev_kfree_skb_irq() or dev_consume_skb_irq() instead.

The CAN FD IP found on RZ/G2L SoC has some HW features different to that
of R-Car. For example, it has multiple resets and multiple IRQs for global
and channel interrupts. Also, it does not have ECC error flag registers
and clk post divider present on R-Car. Similarly, R-Car V3U has 8 channels
whereas other SoCs has only 2 channels.
This patch adds the struct rcar_canfd_hw_info to take care of the
HW feature differences and driver data present on both IPs. It also
replaces the driver data chip type with struct rcar_canfd_hw_info by
moving chip type to it.

For bpf_prog_test_run_skb(), which uses a kmalloc()ed buffer passed to
build_skb().
When build_skb() is passed a frag_size of 0, it means the buffer came
from kmalloc. In these cases, ksize() is used to find its actual size,
but since the allocation may not have been made to that size, actually
perform the krealloc() call so that all the associated buffer size
checking will be correctly notified (and use the "new" pointer so that
compiler hinting works correctly). Split this logic out into a new
interface, slab_build_skb(), but leave the original 0 checking for now
to catch any stragglers.

=======================
The following patch series adds support for a range match action in
SW Steering.
SW steering is able to match only on the exact values of the packet fields,
as requested by the user: the user provides mask for the fields that are of
interest, and the exact values to be matched on when the traffic is handled.
The following patch series add new type of action - Range Match, where the
user provides a field to be matched on and a range of values (min to max)
that will be considered as hit.
There are several new notions that were implemented in order to support
Range Match:
- MATCH_RANGES Steering Table Entry (STE): the new STE type that allows
matching the packets' fields on the range of values instead of a specific
value.
- Match Definer: this is a general FW object that defines which fields
in the packet will be referenced by the mask and tag of each STE.
Match definer ID is part of STE fields, and it defines how the HW needs
to interpret the STE's mask/tag values.
Till now SW steering used the definers that were managed by FW and
implemented the STE layout as described by the HW spec.
Now that we're adding a new type of STE, SW steering needs to also be
able to define this new STE's layout, and this is do

2) From OZ add support for meter mtu offload
2.1: Refactor the code to allow both metering and range post actions as a
pre-step for adding police mtu offload support.
2.2: Instantiate mtu green/red flow tables with a single match-all rule.
Add the green/red actions to the hit/miss table accordingly
2.3: Initialize the meter object with the TC police mtu parameter.
Use the hardware range match action feature.
3) From MaorD, support routes with more than 2 nexthops in multipath
4) Michael and Or, improve and extend vport representor counters.

Intel Wired LAN Driver Updates 2022-12-08 (ice)
Jacob Keller says:
This series of patches primarily consists of changes to fix some corner
cases that can cause Tx timestamp failures. The issues were discovered and
reported by Siddaraju DH and primarily affect E822 hardware, though this
series also includes some improvements that affect E810 hardware as well.
The primary issue is regarding the way that E822 determines when to generate
timestamp interrupts. If the driver reads timestamp indexes which do not
have a valid timestamp, the E822 interrupt tracking logic can get stuck.
This is due to the way that E822 hardware tracks timestamp index reads
internally. I was previously unaware of this behavior as it is significantly
different in E810 hardware.
Most of the fixes target refactors to ensure that the ice driver does not
read timestamp indexes which are not valid on E822 hardware. This is done by
using the Tx timestamp ready bitmap register from the PHY. This register
indicates what timestamp indexes have outstanding timestamps waiting to be
captured.
Care must be taken in all cases where we read the timestamp registers, and
thus all flows which might have read these registers are refactored. The
ice_ptp_tx_tstamp function is modified to consolidate as much of the logic
relating to these registers as possible. It now handles discarding stale
timestamps which are old or which occurred after a PHC time update. This
replaces previously standalone thread functions like the periodic work
function and the ice_ptp_flush_tx_tracker function.
In addition, some minor cleanups noticed while writing these refactors are
included.
The remaining patches refactor the E822 implementation to remove the
"bypass" mode for timestamps. The E822 hardware has the ability to provide a
more precise timestamp by making use of measurements of the precise way that
packets flow through the hardware pipeline. These measurements are known as
"Vernier" calibration. The "bypass" mode disables many of these measurements
in favor of a faster start up time for Tx and Rx timestamping. Instead, once
these measurements were captured, the driver tries to reconfigure the PHY to
enable the vernier calibrations.
Unfortunately this recalibration does not work. Testing indicates that the
PHY simply remains in bypass mode without the increased timestamp precision.
Remove the attempt at recalibration and always use vernier mode. This has
one disadvantage that Tx and Rx timestamps cannot begin until after at least
one packet of that type goes through the hardware pipeline. Because of this,
further refactor the driver to separate Tx and Rx vernier calibration.
Complete the Tx and Rx independently, enabling the appropriate type of
timestamp as soon as the relevant packet has traversed the hardware
pipeline. This was reported by Milena Olech.
Note that although these might be considered "bug fixes", the required
changes in order to appropriately resolve these issues is large. Thus it
does not feel suitable to send this series to net.

Provide a public callback handle_mask_sync() that drivers can use when
they have more complex IRQ masking logic. The default implementation is
regmap_irq_handle_mask_sync(), used if the chip doesn't provide its own
